CORPORATION OF DELAWARE CHICAGO, ILLINOIS, ASSIGNORS, BY MESNE ASSIGNMENTS, TO INDUSTRIAL PATENTS CORPORATION, 0F CHICAGO, ILLINOIS,

Our invention relates to wholesale refrigerated meat packages and methods of making the same, adapted to be used in the shipment by rail or motor truck of fresh meat products, such as require refrigeration, either unfrozen or in a substantially frozen condition. Packages designed for shipments of large quantitIescOntaining about 185 pounds of product areprepared by using an ordinary wooden shipping barrel. We first place a disc of corrugated fiberboard faced on one side, the type of corrugated board commonly known in the trade as Jumbo board, with the facing of the board against the bottom of the barrel. We then a strip of Jumbo board about 26 inches high by 66 inches long, allowing about 6 inches overlap, having the facing turned out. We then insert a waxed bag such as that known to the trade as Arkell, and fold the top surplus over the outer edges of the barrel. We place about 3% to 4 pounds of the solidified gaseous refrigerant, such as solidified carbon dioxide, wrapped in about five la ers of.

wrapping paper at the center of the ottom of the barrel. We then insert an inner Jumbo board liner, that is, a strip about 22 inches long, allowing 6 inches overlap so that the facing is turned inwards, the liner being V-notchecl at the bottom to facilitate CO gas circulation. We then insert a circular wooden rack over the dry. ice and a chipboard circlet on top of the dry ice. Then line the bottom and sides of the barrel with paper circlet and strip respectively, the Jumbo board, since the Jumbo board will collapse if permitted-to become soaked with meat juices. We then fill the container with the(meat product to be shipped, to a maxiof about 1 inch below the top of the inner Jumbo'board liner, cover the product with circlets of packers waxed paper so that the circlet lies within the edge of the indiameter Jumbo K board disc on the top and then place a block of dry ice of about [in five layers of wra ner hner, and place a 14 inch 8 to 9 pounds wrapped ping paper on top of the disc. To prevent s ifting of the dry ice we pack loosely a wad of ordinary crumpled paline the barrel wall with to prevent contact of the product withv per about the block. We then bring the waxed bag closely around the dry ice, twist into a knot, and tie with a string, placing the upper Jumbo board turned out. We then apply burlap over the top of the barrel and cooper the Wooden hoop into place.

We have successfully varied this package by lining the-entire barrel with an excelsior pad, leaving sufiicient overlap to entirely cover the top lining with an Arkell bag, packing in the product and placing a block of dry ice upon a rack or disc at the top of the package, closing the Arkell bag, lapping over the excelsior pad, covering with burlap and coopering on the hoop.

Another variation is to first line with the excelsior padding, placing a block of dry ice on the bottom after first wrapping itin several layers of wrapping paper, placing a woodenaack on the top of the dry ice block,

then linin the sides with corrugated double faced Jum b gets to be so shipped are in relatively small units, a plurality of such units is packed in, the container such that air spaces exist between the several units, permitting the oozing of CO gas throughout the container. It is to be noted that our container is so constructed as to obviate over-freezing when,

shipping fresh product. Referring now to the drawings: Fig. 1 is a vertical central sectional view of a package illustrative of anembodiment of the invention.

disc with the facing Our package eliminates Fig. 2 is a similar viewof a modification. V

Fig. 3 is a detail perspective view of a porof dry "covered tion of a corrugated lining having an edge notchedto provide circulating passages.

In the embodiment of the present invention shown in Figure 1, a barrel having wooden stave walls l'acts as areceptacle in which is placed Arkell bag 2 lined--with'excelsior padding 3\inside of which is placed acorrugated double-faced Jumbo board 4, a block ice 5'being placed at the bottom and with a wooden rack 6, the produpt being then placed in the barrel and a wooden rack 7 placed thereon, on which to hold a larger block of dry ice 8.

Figure the facing of the board against the bottom of the barrel. Ablo'ck of dry ice 5 wrapped ag 2 lined on the inside with a Jumbo board liner 13, being V-notched at the bottpm, as shown in Figure 3, at 14. Inside of the inner liner of Jumbo board 13 is a'waxed paper liner 15. The product is-placed inside of the several insulating walls and liners and covered at the topwith a waxed-paper circlet 16, on which is placed a Jumbo board disc 17 "'to support a. block of dry ice 8, which is wrappedin paper 10. Crumpled paper 18 provides shifting of the dry ice block 8- over which+is closed the Arkell bag 2. On top is placed a Jumbo board disc 19, burlap cover .20 being held in place by hoop 21.

The V-notch 14, which is shown in detailv in Figure 3, permits circulation of cold gas and of refrigerated air space between the productand the barrel walls, as well'as to equalize the refrigeration in the top and bottom of the barrel by permitting free circulation. V

We claim:

paper liner within the last mentioned corrugated liner to receive the meat, a solid refrigerant within the ends of the outer Waxed aper liner, corrugated ends at the top and ottom of the container, and a closure for the container.
